1) The new European standard BS EN 13414-1 for wire rope slings includes two changes that lower the working load limit (WLL) calculation: including the efficiency of rope terminations and restricting the rope grade to 1770.
2) This results in a 10% lower WLL calculation for a given rope diameter compared to the previous British standard BS 1290.
3) Initiatives are being considered to amend the standard to allow higher grade 1960 rope to be used, compensating for the lower efficiency of terminations and maintaining the original WLLs.
This document provides guidelines for the design of steel stacks. It covers terminology, loading considerations, materials, structural design, construction, inspection, maintenance and painting. Key points include:
1. Stack design is complex due to susceptibility to wind and seismic vibrations, as well as corrosion. EPA regulations also emphasize mechanical design.
2. Stacks can be free standing, multi-flue, base supported and braced, or base supported and guyed. Vertical and lateral supports are considered.
3. Stacks may be laterally supported by other structures like towers. Structural interaction must be considered in analysis. Braced stacks require smaller foundations.

This document provides an overview of software testing concepts. It discusses different types of testing like unit testing, functional testing, error path testing, boundary value testing, and equivalence partitioning. It also covers test strategies like golden path testing, black box testing, and white box testing. The purpose of a tester is explained as quantifying risk to make decisions that improve confidence and quality.
This document provides an overview of Gambas, an open-source programming language and integrated development environment. It covers Gambas concepts like variables, data types, operators, control flow statements, and arrays. It also introduces the Gambas Toolbox, which provides common GUI controls like buttons, text boxes, menus and dialog boxes. The document is intended as a beginner's guide to getting started with Gambas programming.
This document provides an overview of the analysis and design of offshore structures. It discusses various types of offshore structures including fixed platforms, compliant structures, and floating structures. It then covers the design methodology, loads assessment, materials selection, corrosion protection, structural simulation, and structural analysis techniques for offshore structures. The document is intended as a reference for the analysis and design of offshore oil and gas platforms.
This document provides a running procedure for installing a Transformer R7 wellhead system. It includes 11 stages of the installation process with detailed steps for each stage. The stages include site preparation, installing the casing head, installing additional components like the drilling adapter, testing the BOP stack, running casing, installing the packoff and casing head cap, and installing the tubing spool. Dimensional drawings and a bill of materials are provided.

Sicurezza antincendio nei luoghi di lavoro v2.3Mauro Malizia
Per la maggior parte dei luoghi di lavoro definiti come "stabilimenti", “impianti”, "industrie", “officine”, “laboratori”, ecc. non sono previste norme “verticali”. In mancanza di norme specifiche occorre fare riferimento ai criteri generali di prevenzione incendi (Art. 15 co. 3 del D.Lgs n. 139/2006).

The document discusses induced pluripotent stem cells (iPSCs), which are adult cells that have been genetically reprogrammed to an embryonic stem cell-like state. Researchers found that forcing the expression of just four factors (Oct3/4, Sox2, Klf4, c-Myc) in mouse cells generated iPSCs that demonstrated pluripotency. Subsequently, similar reprogramming was achieved with human cells by several groups using varying combinations of reprogramming factors. iPSCs show potential for generating diverse cell types and even live organisms, offering opportunities for modeling diseases and developing regenerative therapies.
Port State Control (PSC) allows countries to inspect foreign-flagged vessels entering their ports to ensure safety and environmental compliance. PSC officers check certificates and inspect vessel conditions. Major deficiencies include crew certification and safety issues. Detention occurs when deficiencies make a vessel unsafe to sail. Neither the port state nor owner want long detentions, so time is normally insufficient to void contracts under frustration doctrine. Pre-arrival reporting and inspections involve testing essential equipment and documentation.
